CODEN:LUTEDX/(TEAT-3025)/1-47/(2014) Annual Report 2013 Electromagnetic Theory Electromagnetic Theory Department of Electrical and Information Technology Lund University Sweden Editor: Gerhard Kristensson Lund, September 24, 2014 Preface i Preface With this issue, we celebrate the 25 th anniversary of the Annual Report. These reports have covered the main research and teaching activities in the Electromagnetic Theory Group over the decades. A comparison between activities during the rst staggering years, and the many activities the group now are engaged in, reveals a long scientic journey. There are several reasons for the soaring scientic development of the group  collaboration and scientic diversity have, of course, been important. The spring term of 2013 was stressful for everyone in the group. Several sicknesses made the teaching situation hard. With joint eorts we managed, and we are now very happy to nd the sick persons back to work again. Kristin Persson presented her thesis in June, see Figure 1 and gures on pages 12 and 13, where her thesis is reviewed. This event also brought us the pleasure of a visit to Lund by professor Margaret Cheney, who held a Lise Meitner professor- Figure 1: Kristin ocially nails her thesis on the board in the E-building. ship 2000. The Lise Meitner professorship of Rebecca Seviour ended in June, and we like to thank her for a very fruitful collaboration during her stay with us. We hope the established collaboration will continue in the future. Andreas Ericsson and Doruk Tayli, see Figure 2, started their graduate studies this year, and we wish them good luck with their studies.

This appointment implicates several travel opportunities where he has the possibility to disseminate his research results and to broaden his international network, see Figures 12 and 13 on page 27. As a further example of the success of Mats' research, he was awarded the Best Antenna Theory Paper Award at the European Conference on Antennas and Propagation (EuCAP) in Göteborg. On behalf of the Electromagnetic Theory Group we congratulate him to these well deserved accomplishments. During recent years, our research eorts have been extended with several new collaboration partners, e.g., TICRA, RUAG AB and ESA. These new space applications on EM theory have a lot of potential and they provide us with new interesting scientic challenges. Anther important event was the seminar/workshop in June on frequency selective surfaces. Nader Behdad from University of Madison-Wisconsin was the lecturer, see Figure 14 on page 29. The event was nanced by the Swedish Defence Ma- teriel Administration (FMV), and it is a continuation of the many seminars held by professor Ben Munk at our department during the 00's. In Section 1.6 on page 3 a complete list of external funding during 2013 is presented. Our research critically depends on external funding, and we are fortunate to have support from a number of sources including the Swedish Research Council (VR), European Space Agency (ESA), the Swedish National Space Board, VINNOVA, the Swedish Foundation for Strategic Research (SSF), the Swedish Defence Materiel Administration (FMV), and European Spallation Source (ESS). All these generous supports are gratefully acknowledged. Our research is to a great extent done in collaboration with researchers from leading Swedish industry. This is borne out by the many Adjunct professors that we have in the group, see Section 1.4 on page 3. We see strong mutual benets from both parts in this interaction, and we are looking forward to continuing and deepening this collaboration. Many conferences have been attended by the members of the group during 2013. A list of our eorts at conferences during 2013 is presented in Section 5.5 on page 30. An important event was the URSI International Symposium on Electromagnetic Theory (EMTS 2013) in Hiroshima, Japan, in May. This conference and the work in the international organization URSI engage many of the scientists in the group.

The Faculty of Engineering consists of 19 departments, some of which are divided into divisions. The Electromagnetic Theory Group is within the Department of Electrical and Information Technology. The basis for the research and teaching activities of the group is the application of the fundamental macroscopic electromagnetic laws to the generation and propagation of electromagnetic waves in vacuum or materials. Special emphasis is given to the theoretical study of the various devices that can be constructed to amplify and regulate these eects. In our ambition to achieve these goals, analytical, numerical, and experimental techniques are utilized by the group. The main research activities are concentrated in the area of electromagnetic scattering theory, e.g., antenna and radome applications. Progress in this area is fundamen- tal for the development of devices and technologies that use electromagnetic waves for information exchange. The last few decades have demonstrated an increasing need and demand for technology. During the last decades, wave propagation phenomena in periodic structures has been a prosperous research eld for the Electromagnetic Theory Group. Another important eld of research of the group is related to antennas. The use of multiple antenna systems has received growing interest, both in industry and academia, due to the ability to increase the spectral eciency of wireless communication. In many cases it is desirable to have both high capacity and small physical size. Research in the group has been directed towards establishing physical limitations on information capacity based on antenna size, keyhole eects, and the wave propagation environment. The two largest research facilities in Sweden, MAX IV and the European Spallation Source (ESS), are located in Lund. This is making Lund to one of Europe's major centers for particle accelerator infrastructures. Since 2010 the group has gradually increased research activities in this eld.

Funds for near Research Activities 5 2 Research Activities The current research projects of the group are organized into four main categories: 2.1 Material modeling and electromagnetic interaction 2.2 Electromagnetic scattering and design 2.3 Inverse scattering and imaging 2.4 Antennas and communication 2.5 Accelerator engineering The following subsections give a short general description of the research conducted by the group for each research area above, followed by a list of recent literature produced within the group. Only journal papers are cited explicitly, which serves the double purpose of documenting the researchers involved, and providing key words describing the activities. Full references for conference contributions and technical reports can be found in Sections 3.5 and 3.8, respectively. 2.1 Material modeling and electromagnetic interaction In this research area, the group's focus is on the interaction between electromagnetic elds and material structures. This includes wave propagation in complex materials and structures (inhomogeneous, nonlinear, anisotropic, chiral, frequency selective etc), and mathematical modeling of the physical mechanisms behind the interaction (representations of dispersive eects, homogenization). The primary question in this activity examines the possibility to reduce the amount of information needed to describe the interaction. For example, wave propaga- tion in strongly inhomogeneous media (many parameters) can be modeled as wave propagation in homogeneous materials (very few parameters) if the wavelength is suciently large compared to a characteristic length for the media. This reduction is called homogenization. The properties of the eective homogeneous media must be carefully calculated, usually from a static or quasi-static eld perspective. In another class of problems, interaction on an electronic scale can be modeled with voltages and currents in classical circuit models. Here the major challenge lies in constructing accurate models, including the calculation of circuit parameters from static or quasi-static eld problems. 6 Research Activities 2 2 2 10.5 1 1 12 0 0 1 2 0 2 2 0 1 1 Figure 3: 1 2 15 0 1 2 2 2 2 2 0 1 0 1 −2 −2 0 0 0 2 −2 0 16 11.5 10 0 17 12.5 11 1 0 1 0 2 0 Example of a project under Section 2.1. asymptotics of propagation constant 1 2 Illustration of low-frequency γ(k).

Low-frequency dispersion characteristics of a multilayered Journal of Engineering Mathematics, 83(1), 169184, 2013. 2.2 Electromagnetic scattering and design Under this heading, the scattering problem is of central importance, that is, when a prescribed electromagnetic eld interacts with a particular object (the scatterer), the task is to determine the scattered eld. There is often a particular design goal associated with the scattering, for instance to minimize the scattering for all frequencies, maximize the transmission through a panel for a certain frequency band, or maximize the scattering in order to obtain the most information on the object. The design of complex structures and systems to obtain the design goals relies on the combination of relatively simple physical models to assert the overall function, as well as general or highly devoted numerical codes to compute the specic details of the dierent constituents. Much of our work in this category is performed in collaboration with industry, that often supply the broader systems perspective.

Depending on what is a priori known about the object and scattering situation, dierent strategies may be employed. One alternative is to back propagate the measured eld through a region which is known (usually air), as close as possible to the scatterer, and then see what equivalent currents this corresponds to. Another alternative is to set up several theoretical models of the scatterer, and see which one ts the measured data best. This usually results in computationally demanding algorithms. A more specic set of problems is termed imaging. Here, the aim is to obtain an overall image of the scatterer, for instance its shape or location. This can sometimes be obtained in a relatively straightforward way from the scattering data, especially in the high frequency limit (ray optics). Key journal publications: S. Nordebo, M.

From a system point of view, the antenna suers from several fundamental limitations in terms of available bandwidth, gain etc. versus, for instance, the available volume or complexity in the matching network. New antenna concepts such as MIMO (Multiple Input, Multiple Output) provide new opportunities for increased performance. Our investigations of antennas and wireless systems concern sharpening of fundamental limitations of antennas in various circumstances. We also deal with higher levels of integration, for instance of the antenna with the amplier or the matching network, or the antenna and the surrounding structure, including the interaction of the user.

Since the fall of 2011 we are running a project, nanced by ESS, on the design of the drift tube linac of ESS. The DTL is located in the rst part of the accelerator and accelerate the protons from 3 MeV to 80 MeV. The project is done in collaboration with INFN in Legnaro, Italy, and involves one PhD student, Renato de Prisco. In January 2013 a new project started that involves one graduate student, Gabriele Costanza, and concerns the design of the medium 12 Dissertations, Published papers and Reports Figure 7: Kristin Persson (left), the Faculty opponent Margaret Cheney (right) at the dissertation, June 14, 2013. beta elliptic cavities that are an important part of the ESS accelerator. These cavities are superconducting and are used in the last part of the accelerator. Together with MAX IV Laboratory a project concerning design of RF-units for acceleration and deection of the electron beam has been initiated. The PhD student David Olsson is running this project in collaboration with Lars Malmgren at MAX IV and Anders Karlsson. 3 Dissertations, Published papers and Reports 3.1 Doctoral dissertations Kristin Persson, Radome Diagnostics: Utilizing Source Reconstruction Based on Surface Integral Representations, June 14, 2013, see Figures 7 and 8.

A radome is a cover that encloses an antenna in order to protect it from environmental inuences. Radome diagnostics are acquired in the design process, the delivery control, and in performance verication of repaired and newly developed radomes. A measured near or far eld may indicate deviations, e.g., beam deection, but the origins of the aws are not uncovered. In this thesis, radome diagnostics is performed by imaging the tangential electromagnetic elds on radome surfaces, disclosing the radome inuence on the electromagnetic elds as well as the positions and inuences of defects. The source reconstruction is based on a surface integral representation together 14 Dissertations, Published papers and Reports with the extinction theorem. The extinction theorem and its associated surface integral equation ensure that the reconstructed tangential electromagnetic elds have their sources within the radome. The presence of axial symmetry in the measurement set-up enables usage of the fast Fourier transform to reduce the computational complexity. Furthermore, the problem is solved by an in-house body of revolution method of moments (MoM) code utilizing a singular value decomposition (SVD) for regularization. The reconstruction is performed on a ctitious surface in free space, located precisely outside the physical surface of the radome, i.e., no a priori information of the material of the radome is requested. Moreover, both synthetic and measured data are used to verify the method. The dissertation is composed of ve papers. In the rst three papers, the measurement set-up is a reector antenna covered by a monolithic radome, and the near eld is measured on a cylindrical surface. The height of the radome corresponds to 2943 wavelengths in the frequency interval 8.012.0 GHz. The amplitude and phase of the tangential electromagnetic elds are reconstructed on the radome surface and the inuence of the radome is investigated. Moreover, the alteration of the phase due to the transmission of the radome, the insertion phase delay (IPD), is imaged. Defects in the form of square copper patches, with an edge length corresponding to 1.62.4 wavelengths in the considered frequency interval, are attached to the radome wall. These might serve as a model for e.g., a lightning conductor or a Pitot tube. The attached patches alter the near eld, and by applying source reconstruction, the disturbances of the patches are focused and detectable. In the fourth paper, the eld is measured on a spherical sector in the far-eld region at 10.0 GHz. Two set-ups with dielectric defects attached to the radome surface, are investigated. The aim is to investigate if variations in the electrical thickness of the radome wall can be detected. It is concluded that it is possible to discover dielectric patches of various edge sizes (0.52.0 wavelengths), and with the smallest thickness corresponding to a phase shift of a couple of degrees. In the last paper, a frequency selective (FSS) radome corresponding to a height of 51 wavelengths at the frequency 9.35 GHz is investigated. The electrical perfor- mance of an FSS radome depends on the periodic structure of the elements in the radome frame. The periodic structure of the investigated radome is disrupted by horizontal defects (vertical displacements of elements) and vertical defects (a column of missing elements). The far-eld data is measured on a spherical sector, and the far-eld data reveals that the radome changes the radiation properties. The tangential electromagnetic elds on the radome surface are reconstructed for several antenna illuminations to image the cause of these alterations. Furthermore, it is shown that the dierent components of the electromagnetic elds are aected dierently by the defects, implying that both co- and cross-components of the electric and magnetic elds need to be considered. Moreover, the Poynting's vector is employed to visualize how the defects block the eld from the antenna.

Kristin Persson, Mats Gustafsson, Gerhard Kristensson, and Björn Widenberg, Source reconstruction by far-eld data for imaging of defects in frequency selective radomes, LUTEDX/(TEAT-7224)/1-14/(2013) . Abstract: In this paper, an inverse source reconstruction method with great po- tential in radome diagnostics is presented. Defects, e.g., seams in large radomes, and lattice dislocations in frequency selective surface (FSS) radomes, are inevitable, and their electrical eects demand analysis. Here, defects in a frequency selective radome are analyzed with a method based on an integral formulation. Several far-eld measurement series, illuminating dierent parts of the radome wall at 9.35 GHz, are employed to determine the equivalent surface currents and image the disturbances on the radome surface.

Michael Andersson, Propagators and scattering of electromagnetic waves in planar bianisotropic slabs  an application to absorbers and frequency selective structures, LUTEDX/(TEAT-7225)/1-31/(2013) . Abstract: The concept of propagators for solving scattering problems in pla- nar geometries has been generalized to accommodate thin homogeneous, in general anisotropic, resistive sheets embedded in supporting slabs, by the usage of a well known approximate impedance boundary condition. The slabs can be arbitrary linear materials i.e., bianisotropic materials, and applications of the method to the analysis of single and multilayer absorbers i.e., Salisbury and Jaumann absorbers are given. The generalization of the propagator method also handles the problem with an arbitrary number of metallic sheets consisting of resistive patch elements embedded in supporting linear, bianisotropic slabs. The solution of both the case of nite number of patch elements and the case where the elements are periodically arranged, is shown by the use of the Galerkin method. Numerical examples, where comparison to data presented in the literature as well as measured data, are shown in the paper. TR3. Niklas Wellander and Gerhard Kristensson, Estimates of scattered electromagnetic elds, LUTEDX/(TEAT-7226)/1-28/(2013) . Abstract: We present some general estimates of the scattered electromagnetic elds for a general bounded scattering domain Ω in the anisotropic materials setting. Guests and Seminars 21 In particular, it is shown that the || · ||L2 (Ωs ;C3 ) -norm and sup-norm of the scattered eld in an arbitrary nite exterior domain Ωs are bounded by the H(curl, Ω) norm of the incident eld. Moreover, several estimates of the traces of the scattered eld on the boundary and a circumscribing sphere are presented. TR4. Marius Cismasu and Mats Gustafsson, Antenna Bandwidth Optimization with Single Frequency Simulation, LUTEDX/(TEAT-7227)/1-18/(2013) . Abstract: A method to compute antenna Q using an electromagnetic simulation at a single frequency is described. This method can easily be integrated into global optimization algorithms. In this way the optimization time of some antenna parameters, e.g., bandwidth, may be signicantly reduced. The method is validated by direct comparison with the physical bound of the analyzed structure. Numerical examples for rectangular antennas and antennas with a rectangular ground plane illustrate the integration of the method into a genetic algorithm. The results predicted by optimization agree very well with those obtained using a commercial electromagnetic solver. These results suggest that the method can be used to yield antennas with Q factors within 20 % of their corresponding physical bound. 4 Guests and Seminars 4.1 Visitors at the group of Electromagnetic Theory Nader Behdad, University of Madison-Wisconsin, USA, June 912, 2013.
